Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Postoperative 4-chamber cardiac function and outcomes following biatrial or left atrial Maze procedure for concomitant atrial fibrillationCentral MessagePerspective

JTCVS Open
Objectives: Effects of Maze procedure lesions on subsequent atrial/ventricular function, and clinical outcomes are not well delineated. We analyzed relationships among preoperative atrial strain, postoperative cardiac function, and clinical outcomes ...

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...

Assessment of the left atrial longitudinal myocardial function by the strain and strain rate echocardiography in patients with rheumatic mitral stenosis

, 2011
Aim: To evaluate the regional left atrial (LA) myocardial functions and time to peak deformations by the longitudinal strain (S) and strain rate (Sr) echocardiography in isolated mitral stenosis (MS) patients for 3 LA periods (contractile, reservoir, and

4D ultrasound reveals regional left atrial strain remodelling in a murine model of reversible pressure overload

The Journal of Physiology, EarlyView.
Abstract figure legend Traditional planar imaging approaches of the left atrium do not capture complex geometry. Four‐dimensional imaging allows the acquisition of 3D data + time to visualize left atrial geometry and kinematics. We designed an advanced analysis technique to investigate left atrial biomechanics in a model of pressure overload and ...

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).
